many thanks to SuSE for the analysis: https://www.suse.com/security/cve/CVE-2017-8890/ https://bugzilla.novell.com/show_bug.cgi?id=1038544 - CVE-2017-8890 https://bugzilla.novell.com/show_bug.cgi?id=1039883 - CVE-2017-9075 https://bugzilla.novell.com/show_bug.cgi?id=1039885 - CVE-2017-9076 https://bugzilla.novell.com/show_bug.cgi?id=1040069 - CVE-2017-9077 We will need at least: 1) 657831ffc38e dccp/tcp: do not inherit mc_list from parent 2) 83eaddab4378 ipv6/dccp: do not inherit ipv6_mc_list from parent - CVE-2017-9076 and CVE-2017-9077, they split the fixing commit into the dccp and ipv6 part for CVEs. 3) fdcee2cbb843 sctp: do not inherit ipv6_{mc|ac|fl}_list from parent - CVE-2017-9075 Second commit addresses the same issue for DCCP over IPv6 and third commit for SCTP over IPv6. Commit message of 657831ffc38e also mentions: 4) 8b485ce69876 tcp: do not inherit fastopen_req from parent which addresses similar problem found by syzkaller. This one is already in 4.4 and 4.11 but not in older branches. This one doesn't seem to have a CVE id assigned (or at least not one with open bug in bugzilla). 8b485ce69876 should be backported to 3.10 kernel, older kernels do not need it as TCP fast open was only added in v3.6-rc1.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '25'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This was fixed for Fedora with 4.12 kernel updates.
